What is the Function of a Manual Transmission?

[Kyle]

The function of a manual transmission is mainly reflected in three aspects. First, it changes the transmission ratio to expand the range of torque and speed variation of the driving wheels. Second, it allows the vehicle to reverse while maintaining the engine's rotation direction. Third, by using the neutral gear, it can interrupt the engine's power transmission, enabling the engine to start or idle. A transmission is a mechanism used to alter the speed and torque from the engine. It can fix or change the transmission ratio between the output shaft and the input shaft in steps, hence also known as a gearbox. The transmission consists of a gear shifting mechanism and a control mechanism, with some vehicles also featuring a power take-off mechanism. Most transmission mechanisms use ordinary gear systems, while some employ planetary gear systems. Ordinary gear transmission mechanisms typically use sliding gears and synchronizers, among others. Changing the transmission ratio meets the need for traction under different driving conditions, allowing the engine to operate as much as possible under favorable conditions and meeting the required driving speeds. It enables a wide range of adjustments to the vehicle's speed and the torque on the driving wheels. Since driving conditions vary, the vehicle's speed and driving torque need to be adjustable over a wide range.
